Pep Guardiola has led his side to 15 straight victories in all competitions (albeit one League Cup win on penalties) and it doesn't look like anyone is going to stop them anytime soon.

It has taken a good year for Guardiola's ideologies and investments to come to fruition, but patient City are now seeing the results of his intricate plan.

On the pitch, City are very much beginning to look like Guardiola's world-beating Barcelona side.

But it's not just tactical genius that has got City to the position they are currently in.

Guardiola has made significant changes behind the scenes at City - and the Daily Mail have rounded up the key aspects in what makes the ambitious club what they are today.

TOGETHERNESS

Team spirit and morale is absolutely crucial for Guardiola.

Before joining City, he made sure that he knew the nicknames of every single one of his players.

Now, it is reported that he is close to knowing every single member of staff's name that he has any dealings with around the club, whether it be the chefs or the accountants.

To help build team spirit, Guardiola regularly sends his squad out for meals together, while he also ensures they spend breakfast and lunch as a team in the canteen at City's spectacular Football Academy base.

TRAINING

Guardiola's tactical approach to football is one of the most detailed in the whole of the game, so it takes a lot of time and hard work on the training ground to get right.

The sessions have been described as intense, but Guardiola is insistent that training has to be enjoyable for the players, to help keep them motivated.

He'll also regularly draft in the youth team players for the sessions - but not always to play alongside the multi-millionaire superstars that City have.

The youth team will often play against the first-team, instructed to play in the same style as some of City's upcoming opponents.

ANALYSIS

Guardiola is keen to make sure his players know exactly what he wants, so he calls them into analysis meetings every single week.

The squad will gather in what is effectively a university lecture hall and the Catalan will deliver speeches on what he expects from every player.

He'll use the large video screens to deliver his message in as much detail as possible.

FOOD

City have employed chefs from England, France and Spain since Guardiola has arrived at the club.

Nutrition and a healthy diet is especially important to Guardiola, given the amount of work that he asks his players to do on the training ground.

One member of staff that Guardiola has brought over from Spain is nutritionist Silvia Tremoleda, who regularly posts images on her Instagram page of what she is serving up for City's players.

She was known for helping Lionel Messi get back to full fitness when he suffered an injury setback.

Players at City are encouraged to take doggy bags of food home with them, to help them stick to their strict diets.

HEALTH

Players are subjected to regular health checks at City, with blood tests often on the agenda.

Guardiola has increased the size of the physiotherapy team since joining the club, with no less than 10 medics and two doctors currently working with the club.

The day after every game, players head into cryotherapy chambers to aid their recovery.
